The purpose of this research was to investigate and compare the electrochemical characterization of new cathode materials LiNi0.7Co0.2Fe0.1O2 and Li1.1Ni0.6Co0.2Fe0.1O2. The materials were prepared using a combustion synthesis method. Composite cathodes were fabricated and assembled in a coin-type cell. The discharge profile showed plateaus at 3.7 V and 1.6 V. The overlithiated sample exhibited a 10.4% increase of discharge capacity in the first cycle of and an increase of 43.7% in the 5th cycle compared to the non-overlithiated sample.

Scherrer Formula

Nanocrystalline ZnO powders have been synthesized by a novel combustion synthesis method using glycine and urea as mixed fuels and zinc nitrates as oxidant. The as-synthesized ZnO powders are characterized by DSC, XRD and SEM. Results show that the as-synthesized ZnO powders show well crystalline with hexagonal crystal structure and purity without any other impurities and the particle sizes are about 50~70nm calculated by the Scherrer formula.
